What Is Hamnet
Hamnet is a historical weather dataset covering parts of Europe from the late 18th to early 20th century. It provides daily temperature, precipitation, and pressure observations compiled from station records.
How Accurate Is Hamnet
Hamnet accuracy varies by region and period. In well-documented areas with long station histories, data are generally reliable for temperature and precipitation trends. In regions with sparse records, accuracy is lower and gaps are common.
Limitations and Best Uses
Hamnet does not include modern quality-controlled metadata, and some values may reflect station moves or instrument changes. It is best used for large-scale climate analysis rather than precise local forecasts. For more on data sources and methodology, see KNMI Climate Data.
